Hey. First post here. Got the zeiss 16-70mm f/4 yesterday. It's razor sharp and perfect for my needs as an amateur photographer. I've only ever used the sony 35mm 1.8 to shoot since I bought my 3N and the one thing I've noticed is at the longer focal lengths, the depth of field is tiny at f4 when shooting close to a subject. Say 3-4 feet away, the DoF us like 4 inches. Do most people then not shoot at f4 at 60-70mm close up?
